Education in radiology involves a large portion of practical training, and it is difficult to conduct it through non-face-to-face online education. In this study, we utilized the Metaverse platform, which can replace hands-on education, to implement a practice room that is difficult to access through non-face-to-face classes into a virtual world, and then evaluated the satisfaction of learners after the practice class, the practicality of the Metaverse platform class, and the future orientation of the curriculum. I wanted to find out. Using the metaverse platforms ZEPETO (Build It) and ZEP (ZEP), the S University radiology department lab was implemented into a virtual world and used for students' classes. A total of 50 students were surveyed twice, divided into pre- and post-surveys, and all questions used a 5-point Likert scale. As a result of the study, satisfaction was low at 2.32 for education without using Metaverse virtual space, while education using virtual space was very high at 4.16. As a result of the analysis, the satisfaction level of the new education system and the practicality of the Metaverse platform classes are very high, and it is believed that it will be a more effective education platform when conducting additional education such as app explanations in the future.

The aims of this study were to validate the Occupational Basic Competencies of Fisheries and Maritime High school. Fisheries & Maritime key competencies were defined as the abilities that include the essential knowledge, skills, attitude, and experiences required for the workforce on the fisheries and maritime job condition. This research collected preliminary data from 1,113 fisheries & maritime high school students. Data were analyzed to obtain reliability and validity analysis. The results of the study were as follows; First, fisheries & maritime key competencies were divided into 6 elements. Second, fisheries & maritime key competencies were consisted of marine vocational ethics, marine information capacity, marine elementary knowlegde, marine safety management skill, management & utilization of marine life and marine consciousness. Third, Cronbach-${\alpha}$ proves that the scale developed in the study is reliable. In consequence, the results of this study help to reconceptualize fisheries & maritime and apply the scale to measure students in high school settings.

이 연구의 목적은 (가)학생들의 "공기중의 물"에 대한 직관척 견해와 그 특성들을 파악하여 기술하고, (나) 나이와 학습 능력의 증가에 따른 직관적 견해의 분포 및 변화 경향의 파악 및 기술(description)에 있다. 미국 텍사스주 중부에서 36명의 연구대상 학생들이 선발되었다(5-, 8-, 11-학년 및 대학교 학생 각각 9명씩). 대학생들을 제외한 각 학년은 3명 씩의 우수, 보통 및 열퉁 학생들로 구성되었다. 연구 방법은 현상에 대한 면담법(Interview-About-Phenomena)이 사용되었다. 대기 중의 물은 7개의 종속개념(수증기, 습도, 증발, 웅결, 승화 I 과 II, 그리고 이슬점)으로 세분되어 조사되었다. 연구 결과 각 종속개념마다 3개에서 7개까지 여러 직관적 견해들이 파악되었다. 학년과 학습능력이 증가 할수록 학생들은 더 정교한 직관적 견해를 보유하고 있었다. 파악된 직관적 견해들의 재구성(restructuring) 또는 보다 정교한(more sophisticated) 견해로의 변화는 종속개념에 따라 다르다. 직관적 견해들이 재구성되기 쉬움에 따라 종속개념들을 배열한 것올 "재구성 계열"(Restructuring series)이라 정의 하였으며 이는 다음과 같다. 수증기-습도-이슬점-응결-중발-승화 I 과 II. 이 연구의 결과는 과학교수 전략 및 과학 학습교재의 고안과 개발, 과학교사 양성과정, 그리고 과학학습 평가 등에 활용되어져야 할 것이다.

In this paper, we proposed a method to find out similar sentences from documents to detect plagiarized documents. The proposed model adapts LSA and N-gram techniques to detect every type of Korean plagiarized sentence type. To evaluate the performance of the model, we constructed experimental data using students' essays on the same theme. Students made their essay by intentionally plagiarizing some reference documents. The experimental results showed that our proposed model outperforms the conventional N-gram model, Vector model, LSA model in precision, recall, and F measures.

Using a sample of 83 secondary school science teachers, this study investigated the views on science and learning which they have. Questionnaires used in this study were the same that Kwon & Pak(1995) administered. Both 'Questionnaire for Perception of Nature of Science' and 'Questionnaire for Constructivistic Views of Learning' were 11-point scales. Data analyses were done by using t-test and ANOVA. The secondary science teachers showed a relativistic, deductivistic, instrumental, and process-oriented views on science. The younger age of the teachers, the more emphasis on process rather than content. Female teachers had more relativistic, instrumental, and process-oriented views than male teachers had. The teachers sampled in this study showed a constructivistic view on learning. Finally, the teachers' views of science and learning were closely related each other.

Although the educational institutions of computers have evolved to train students in pace with the changes of computing, many students still believe that computer programming is hard to be mastered. The reluctance of students toward programming languages have been tied to the decrease of computer-related majors and now many countries are in short of computer programmers. By investigating the similarities among eleven popular programming languages, this research is intended to measure the relative distances and understand the dimensions that scattered the languages.

The degree of fatigue that first-aid staff feel got 2.09 point (SD.49) out of 4. The degree of job satisfaction of 119 first-aid staff got 2.71 point out of 5. This study suggests increasing of new hire, continuous education through teaching before employment, studying abroad, and so on, expansion and modernization of first-aid equipment, introduction and management of OAT institution for improvement of job satisfaction of first-aid staff.

This study sought to investigate and assess the development patterns of children, aged from 3 to 5, by means of a longitudinal approach. The children's developmental patterns are classified according to five curriculum areas; physical health, social skills, expression, language, and exploration-. The developmental patterns are analyzed in detail according to the observation period, children's ages, and their genders. The subjects consisted of 108 children in A city. A research assistant was asked to observe and keep records of the children's behaviors at three distinct times -early, middle, and late in the school year. The 'observational scale for children' was used as the measurement tool. The data which was thus collected was then subject to statistical analysis. The major findings of the study are as follows. First, there were significant differences in all five curriculum areas according to the children's age and observation period. That is, five-year-old children showed higher scores than three- and four-year-old children. Second, there were significant differences in the social development within five curriculum areas according to the children's gender and the observation period. That is, girls exhibited higher scores than boys.

To investigate the pupils' ideas about appropriate scientific inquiry problem, we have chosen the 105 boys and girls of 7th grade in a middle school in Seoul, Korea. Their marks in science are within the highest one-third of their classes. The pupils have made their own scientific inquiry questions, which is to be investigated by themselves in summer vacation. The 105 inquiry questions were gathered and evaluated by the pupils with 5-point Likert scale. From these, we have found that the questions inquiring novel phenomena, questioning causality, or containing scientific terms were evaluated as appropriate. Some questions were changed during performance. The pupils have changed their inquiry problems if they feel any difficulties in performing the inquiry.
